- 1 An extension of low atmospheric pressure from the central regions of a low-pressure system into a zone where generally higher pressure prevails. The term ‘trough’ is also, and in accordance with this definition, applied to equatorward meanders of the flow of the upper westerly winds over middle latitudes.

Aug 9, 2024 · Learn about the formation of glacial landforms from corries to troughs, along with examiner tips and worked examples for the AQA GCSE Geography exam.
In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench, a trough can be a narrow basin or a geologic rift. These features often form at the rim of tectonic plates. There are various oceanic troughs on the ocean floors.
Jun 22, 2024 · A trough is often associated with cloudy conditions, precipitation, and sometimes even a cold air mass. On the other hand, a ridge indicates relatively higher heights and is typically characterized by sinking air. This sinking air within a ridge tends to bring warmer and drier weather.
These are valleys formed by the glacial processes of weathering, erosion and transportation. They have steep sides and flat floors. Unlike V-shaped river valleys, glacial troughs are straight as they have truncated any interlocking spurs which existed prior to glacial advance.
In geology, a trough refers to a linear depression that extends in one direction over a distance. It is less steep than a trench. A trough can be a narrow basin or a geologic rift. There are various oceanic troughs, troughs found under oceans; examples include the rifts along the mid-ocean ridges

Oct 24, 2023 · A weather trough, often referred to simply as a trough, is an elongated region of low atmospheric pressure within the Earth’s atmosphere. Troughs are part of the broader atmospheric circulation patterns. They are typically associated with regions where the air is rising.
